In this work, a class of good ternary codes sets are introduced. First, mutually orthogonal vectors are selected, then they are spread via a Golomb ruler. This is shown to result in such a good set. If the mutually orthogonal vectors have entries in {-1,1} or {-1,0,1}, then a ternary code set result. While there are methods of generating ternary codes, and complementary ternary codes [1–7], there is no method in prior publications of generating mutually orthogonal ternary code sets. That is one of the contributions of this work. If complex numbers with unity magnitudes are allowed, then we obtain codes with magnitudes in {0,1}. If the vectors are obtained from matrices with mutually orthogonal rows and columns, as in Hadamard matrices, or DFT matrices, then longer codes can be obtained via spreading the obtained good set via a Golomb ruler a second time. Using existing codes, such as Barker codes, and spreading them via a Golomb ruler, then compounding them with the elements of a good set, results in a new good set with higher mainlobes. The spreading could be induced via any array of any dimension with elements of magnitudes in {0,1} that have autocorrelation with unity peak sidelobes. This includes Costas arrays, in addition to Golomb rulers.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122287692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The target is positioned in the near-field of a network of radars of arbitrary geometry. The radars have ideal mutual time and phase synchronization. The target location is estimated by coherent processing exploiting the amplitude and phase information between pairs of radars. An analytical expression is developed for the ZZB relating the estimation mean square error (MSE) to the carrier frequency, signal bandwidth, the number of sensors, and their location. From numerical calculations of the bound, three regions of signal-to-noise ratio (SNR) can be distinguished in the performance of the location estimator: a noise-dominated region, an ambiguity region, and an ambiguity free region. In the noise-dominated region, the signals received by the radars are too weak, and thus the localization error is limited only by the a priori information about the location of the target. In the ambiguity region, the performance of the location estimator is affected by sidelobes. In the ambiguity free region, estimation errors are very small and the ZZB approaches the Cramer-Rao lower bound (CRLB).","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127991208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the target tracking, the tasks are required to be executed to consider the maneuvering motion, measurement condition and required tracking performance. Frequent execution of tracking tasks results in not only precise tracking, but also waste of timing resource which is shared with other functions. Therefore, to reduce the number of unnecessary observations, the tracking task is required to be executed only when the update is needed. In this paper, the innovation, position residual, in Kalman filter is used as reference value for adjusting update rate of tracking tasks. Using feedback controller, the update rate is allocated so that predicted observation is expected to be within specified error range. In addition, targets are classified into 7 priorities according to tactical characteristics, and target's priority is also used as reference value for calculating update rate. The simulation results show that the proposed method reduces the tracking error of the target on maneuvering movement compared to fixed update rate case.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132793374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
